What are the advantages and disadvantages of the high-protein diet?

The high-protein diet is a 4-step weight loss program allowing for rapid and effective weight loss. It can be followed by anyone wishing to lose weight without deprivation thanks to more than 100 available flavors. The protein diet for weight loss therefore has many advantages, but also some disadvantages that we will see below.

The high-protein diet consists of consuming high biological value proteins, mainly in powder form, while limiting carbohydrate and fat intake. The goal is to lose fat mass without sacrificing muscle mass.

There are two types of protein-rich foods: those of animal origin (meats, fish, dairy products, shellfish, seafood) and those of plant origin (cereals, legumes, lentils, green beans, peas, etc.). Slow and fast sugars, such as starches and carbohydrates, are excluded from the diet, at least during the initial phases.

During the high-protein diet, the body is deprived of sugar and begins to use its fat reserves as an energy source. This gradually reduces the feeling of hunger and decreases cravings for snacks.

The high-protein diet is generally divided into four phases:

1. Strict protein diet : It involves the exclusive consumption of high-protein sachets, allowed vegetables, and adequate hydration. Vitamin and mineral supplements may be recommended for prolonged diets. This phase initiates the ketosis process, where sugar and fat reserves are depleted.

2. Mixed protein diet : High-protein sachets are reduced to 4 or 5 per day, while dietary proteins are reintroduced. Vegetables remain essential and hydration continues with a minimum of 2 liters of sugar-free drinks per day.

3. Transition : Carbohydrates and lipids are gradually reintroduced. Three meal substitutes are consumed per day, and a codified breakfast including fruits and natural proteins is added. The rest of the day includes a slimming meal with animal and/or dairy proteins and vegetables.

4. Stabilization : Food quantities gradually increase, and starches are introduced. A codified breakfast is maintained, as well as two slimming meals with vegetables and starches. Two snacks can be chosen from high-protein sachets, bars, or high-protein biscuits. This step promotes a permanent transition to a balanced diet and the resumption of healthy eating habits.

At the end of the high-protein diet, the weight is stabilized. It is important to maintain good eating habits acquired during the diet to avoid regaining the lost kilos. The last phase of the diet helps adopt new eating habits.

The advantages of the high-protein diet are numerous: decreased hunger sensation, ease of the diet, quick and effective weight loss, simplicity of consuming high-protein sachets, maintenance of muscle mass, targeted weight loss on fat mass only, no yo-yo effect, ...

The feeling of hunger decreases: Proteins have a natural "appetite suppressant" effect. They remove the desire to snack and take away the feeling of hunger for several hours. Indeed, their slow digestion gives us a longer feeling of satiety. Protein is therefore your slimming ally in many weight loss programs.

Ease of the high-protein diet: Once you've ordered your high-protein products, you just have to prepare them (often simply with a shaker and water), and you just need to add your allowed vegetables to lose weight and start your diet. At stage 2, you will have a meal consisting of lean meat accompanied by vegetables.

Speed and effectiveness of the protein diet: With the protein diet, weight loss is significant but above all very fast and effective! The average loss observed at the beginning of the diet is 2.5kg per week. Losing weight through a low calorie intake is the simplest way to deal with overweight, following a low-calorie diet to tap into your reserves is therefore the solution!

Simplicity of an effective diet: Higher protein consumption boosts metabolism. The body uses more energy and therefore more calories to digest proteins than to digest lipids or carbohydrates. Thus, even when inactive, the body burns more calories.

Fewer calories in the body: Proteins are low-calorie foods, they only provide 4 kcal per gram, while carbohydrates (present in large quantities in starches, for example) and lipids provide 4 and 9 respectively per gram. This low calorie intake will allow you to lose weight quickly.

Motivation to continue the diet: The high-protein diet allows for effective and rapid weight loss, which motivates you from the first weeks to continue your diet. Don't give up!

Maintenance of muscle mass: This diet is the one that best protects muscles, unlike other diets. Thanks to a massive intake of protein, weight loss occurs in the reserve fats and adipose mass, while preserving muscle mass. Engaging in physical activity (walking, running, yoga...) is recommended but not mandatory for losing weight with the high-protein diet.

You can also enjoy your protein sachets (composed of a very complete amino acid profile) as a snack after your weight loss diet.

Stay regularly hydrated: The high-protein diet puts more strain on the kidneys due to the significant protein intake. This is absolutely not dangerous for health, but it is important to drink plenty of water during the high-protein diet period, about 2 liters of water per day.

Risk of long-term fatigue: Indeed, the absence of carbohydrates in the diet leads to a lack of energy and can cause fatigue (hence the importance of taking a vitamin supplement from day 1 of the diet). Gerimax is full of vitamins and minerals that will help you stay in shape. However, phase 1 is not mandatory and you can start your diet directly with phase 2.

A slowed social life: It's obvious that during your diet you'll need to adapt your social schedule and limit invitations with friends and family... At least during the strict diet phase, it's important not to be tempted, so it's better to avoid restaurant outings.
It's important to maintain a social life to keep good mental balance and stay motivated. We therefore recommend informing your close circle so you can bring your high-protein meal and enjoy these moments of conviviality without deprivation. Additionally, you'll be proud to show your progress to your loved ones.

No dietary deviations are allowed: Even a small piece of bread, for example, can make you exceed the 50g daily carbohydrate limit and break the ketogenesis process. Quick tip: if you feel like you're about to give in, take an extra sachet but don't ruin all your efforts for a small slip-up (especially valid in Phase 1), and if this phase no longer suits you, contact your doctor or our Laboratory to study the best personalized solution and  guide you if needed towards phase 2 with the reintroduction of dietary proteins.

Obligation to follow the weight loss program: It is imperative to complete all food reintroduction phases (phases 3 and 4) to obtain a permanent result and avoid the yo-yo effect common to most rapid diets.

Bad breath: You may experience bad breath, which is completely normal. This is caused by the evacuation of acetone through the lungs. If this happens, stay positive - it means your diet is working well. Simply take  a sugar-free chewing gum or a menthol breath spray to avoid this inconvenience.

To conclude, the high-protein diet has many advantages but also some disadvantages. For example, it allows for very rapid weight loss (up to 2.5 kilos per week) but it is better to limit deviations if you want your diet to be effective.
